Question

(BEST ANSWER GETS MEDAL!) Recall that a point (x,y) lies on the graph of an equation if its coordinates satisfy the equation. Assume that the points (1,2), (3,-8) and (-1-4) lie on the graph of the equation y= ax^2 + bx + c. Use this to set up a system of three equations and three unknowns: a,b, and c. Solve the system and determine the equation that these points lie on the graph of.
